 ====== PPI (Participant Provided Information) ======
-PPI is a coding system for questionnaires and self-completed surveys, that is provided by the All of Us Research Program.
+Thank you for visiting the wiki! This page has moved to https://github.com/OHDSI/Vocabulary-v5.0/wiki/Vocab.-PPI.
-**Source**
-All PPI information is manually obtained from the All of Us PPI Codebook.
-**Layout**
-PPI Questionnaire layout consists of Modules, Topics, Questions, and Answers.
-^ PPI source type value  ^ Description                                                                                                                                                                                                                                                                                                                                                ^
-| Module                 | A superior PPI entity representing a thematic set of topics, questions, and answers.  \\ Currently, the following Modules are available: \\ 1) Consent PII\\ 2) Refresher Consent\\ 3) EHR Consent PII\\ 4) Family History\\ 5) Personal Medical History\\ 6) Healthcare Access & Utilization\\ 7) Lifestyle\\ 8) Overall Health\\ 9) The Basics\\ 10 PMI  |
-| Topic                  | A semantic module section containing a thematic set of questions or answers                                                                                                                                                                                                                                                                                |
-| Question               | A multiple-choice or open-ended question requesting information                                                                                                                                                                                                                                                                                            |
-| Answer                 | An answer representing a defined statement or free text                                                                                                                                                                                                                                                                                                    |
-**Concept Names**
-PPI source names are represented in a “display” field. However, to avoid concept name duplicates, modified PPI names have been made through the parsing of their source codes (values of a “pmi_code” field). Original “display” values were put into the CONCEPT_SYNONYM table.
-**Standard concept**
-If a PPI concept has a standard LOINC or SNOMED equivalent, it is considered to be Non-standard.
-If a PPI concept does not have a standard LOINC or SNOMED equivalent,  it is considered to be Standard.
-**Domains and Concept Classes**
-^ PPI source type value  ^ Concept Class         ^ Domain        ^
-| Module                 | Module                | Observation   |
-| Topic                  | Topic                 | Observation   |
-| Question               | Question              | Observation   |
-| Answer                 | Answer                | Observation   |
-| Protocol modification  | PPI Modifier          | Observation   |
-| Physical measurement   | Clinical Observation  | Measurement   |
-**Internal PPI relationships**
-A purpose of Internal PPI relationships is to build a PPI Hierarchy, which makes it easier to understand the relations between PPI concepts of different types.
-**External PPI relationships**
-A purpose of Internal of External PPI relationships is the following:
-to build PPI-LOINC-SNOMED hierarchical crosswalks based on the Internal PPI Hierarchy.
-to simplify s cross-analysis of patient-related information with a context of combined use of the PPI and such a coding system as either the LOINC or SNOMED.
-**Hierarchical crosswalks**
-The PPI Hierarchical crosswalks include only standard concepts. A PPI standard concept value depends on the existence of an equivalent mapping either to the SNOMED or LOINC. In turn,  a standard SNOMED/LOINC equivalent, if present, takes place of a non-standard PPI concept in the Internal PPI Hierarchy and adopts all its ancestors and descendants.
